Apple’s latest-generation Apple Watch doesn’t just have a curved display and a new industrial design — new major features of the Watch at launch last year include its advanced health-tracking capabilities, particularly in regards to heart health and AFib detection.

Those features arrived in the U.S. in December, but users abroad have had to wait. Today, Apple announced that the electrocardiogram feature and irregular-rhythm-detection functionality is coming to 19 European countries and Hong Kong in the Watch’s latest update. These users will also gain access to the irregular-rhythm-detection features available on Watch models Series 1 and later.

Irregular-rhythm detection is available on Apple Watch Series 1 and later. The ECG app is only available on the Apple Watch Series 4, but if you’re a European or Hong Kong-based user and curious about the new capabilities, update your Watch to 5.2, then open the Health app on your updated iPhone and go through the on-boarding process.
